Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat retaining device for a moving device with various engines.

[0002]

2. Description of the Related Art In recent years, passenger cars, large cars, large ships and the like have been equipped with air conditioning units so that they can be operated even in winter without feeling cold. However, in vehicles such as motorcycles and motor boats where the driver is exposed to the open air, it is difficult to heat the vehicle, so the driver wears winter clothes, but if normal winter clothes cannot withstand the cold. There are also many. The situation is the same for construction machines such as bulldozers and crane trucks, or agricultural machines such as tractors and combine harvesters. In such a case, a disposable body warmer is attached to clothes or stored in a pocket to prevent cold, but a body warmer is the root cause of the cold when sitting for a long time in the seat of a vehicle. Sticking has a resistance in appearance, and not only does it feel uncomfortable due to the uneven shape of the body warmer, but over time, the body warmer becomes rigid and pain occurs in the user's thighs, buttocks, etc. There is a problem.

Further, even in a passenger car or a large car equipped with a heating / cooling device, it is difficult to continue heating for a long period of time during operation stop because of heavy battery consumption. That is, for example, when going to a remote place by skiing, fishing, or other outdoor sports, a passenger may depart to the destination before dawn or the night before the day. In the winter, in order to avoid weather changes such as snowfall and traffic congestion, schedule and act so that you can arrive at your destination with more time than you plan to start skiing or fishing.
In such a case, when the vehicle arrives earlier than the scheduled time, it is often parked to take a nap in the vehicle to rest the tired body. Similarly, even during long-distance driving or long-distance truck transportation, you may park and take a nap in the car to recover fatigue from the driver or passengers or to adjust the estimated arrival time. . In winter, the engine cannot be napped in the cold unless the room is heated by radiating the engine and generating electricity during the nap. However, engine noise and vibration, fuel consumption, and exhaust gas emission lead to problems of environmental protection and cost.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be specifically described below with reference to the drawings. First, the first aspect of the present invention shown in FIGS. 1 to 3 will be described. FIG. 1 is an explanatory view showing an embodiment in which the heat retaining device according to the first aspect of the present invention is applied to a motorcycle seat, FIG. 2 is a sectional view showing a structure of a mat portion thereof, and FIG. It is explanatory drawing which shows one Example of a body. In the figure, 1 is a heat storage body, 1a is its container, 1b is a heat retaining agent, 2 is a heating plate, 3 is a mat that constitutes a seat, 4 is a heat transfer body, 5 is a heat buffer, D is a motorcycle engine, and E1. Is an engine exhaust pipe, and F1 is a muffler.

The heat storage body 1 housed in the mat 3 is formed by filling a sealed container 1a made of polypropylene or the like with a heat retaining agent 1b which absorbs and releases latent heat according to a phase change. As the heat retaining agent 1b, for example, sodium sulfate decahydrate is used. In this case, the heat retaining agent 1b is solid at room temperature, but when heated to a certain temperature, for example, 32 ° C. or more, a large amount of heat becomes latent heat. Absorbs and turns into a gel. When it cools and solidifies, it has the property of maintaining about 30 ° C. for a long time by gradually releasing the stored latent heat. The temperature of this phase change can be freely changed depending on the composition of the heat insulating material 1b.

As shown in FIG. 2, on the lower surface of the heat storage body 1,
Heating plate 2 made of aluminum or the like so as to be in close contact with it
Is attached. The heating plate 2 is heated by the heat transferred from the exhaust pipe E1 of the engine by the heat pipe 4, transfers the heat to the heat storage body 1 and stores the heat therein. The mat 3 is made of a material having appropriate flexibility and heat insulation.

The heat transfer body 4 plays a role of transmitting heat from the outer wall surface of the exhaust pipe E1 which is the exhaust heat release portion of the engine to the heating plate 2. In the illustrated embodiment, the heat transfer body 4 is a heat transfer body. A pipe is used, one end of which is attached to the outer wall surface of the exhaust pipe E1 via the thermal buffer 5, and the other end of which is attached to the heating plate 2 as described above. The heat pipe 4 is formed by covering the inner wall surface of a pipe made of stainless steel or the like with whiskers or other hairy bodies, enclosing a small amount of working fluid in the pipe, and then removing the air in the pipe to seal it. It is a device. The heat is absorbed by the evaporation of the working fluid at one end of the pipe (in the illustrated embodiment, a portion attached to the outer wall surface of the exhaust pipe E1) and is transported together with the steam, and the other end (the illustrated embodiment is performed by the condensation of the steam). In the example, the part attached to the heating plate 2) operates to be emitted. Therefore, the thermal conductivity of the heat pipe is several tens of times that of a copper rod of the same thickness.
It has excellent heat transport performance of several hundred times.

The heat transfer body 4 does not necessarily have to be a heat pipe, but may be a metal strip having a high thermal conductivity, such as aluminum or copper, and especially from the exhaust heat release portion E1 of the engine. When the distance to the heating plate 2 is short, such a metal strip can sufficiently achieve the purpose. Furthermore, the heat transfer body 4 may be covered with a heat insulating material so that heat is not lost in the heat transfer path from the exhaust heat release portion E1 of the engine to the heating plate 2.

Thus, the exhaust heat release portion E1 of the engine is
Usually, since the temperature reaches a high temperature, in the present invention, a heat buffer 5 which can adjust the thermal conductivity between the exhaust heat releasing portion E1 and the heat transfer body 4 is provided between the heat transfer body 4.

The thermal buffer 5 has a structure in which a cylindrical heat transfer member is divided into two along the axial direction,
With respect to one fixed semi-cylindrical body 5a, the other movable semi-cylindrical body 5b can slide in the axial direction. Therefore, when the movable side semi-cylindrical body 5b is lifted upward in the figure, the contact area between the semi-cylindrical body 5b and the heat transfer body 4 decreases, and the heat transfer coefficient from the exhaust pipe E1 to the heat transfer body 4 is reduced. On the contrary, when the semi-cylindrical body 5b is pushed downward, the contact area between the semi-cylindrical body 5b and the heat transfer body 4 increases, and the heat transfer coefficient from the exhaust pipe E1 to the heat transfer body 4 is reduced. Get higher In this way, by appropriately moving the movable side semi-cylindrical body 5b,
The heating temperature of the heat storage body 1 can be adjusted by adjusting the heat transfer coefficient from the exhaust pipe E1 to the heat transfer body 4.

The structure of the heat buffer 5 which can adjust the thermal conductivity between the outer wall surface of the exhaust heat emission site E1 and the heat transfer body 4 is not limited to that shown in FIG. A jacket filled with water is attached to the outer periphery of E1, and one end of the heat transfer body 4 is housed in the jacket, and the water in the jacket can be circulated with a water tank separately provided,
By making it possible to adjust the circulation flow rate with a valve etc.,
It is also possible to adjust the thermal conductivity.

Furthermore, it is possible to provide a control device that detects the temperature of the heat storage body 1 or the heating plate 2 and automatically adjusts the thermal conductivity of the thermal buffer body 5 so that the temperature is kept substantially constant. .
